The ServoDyn module seems doesn't work #165

Closed DLUT-cabbage closed 4 months ago

DLUT-cabbage commented 1 year ago

Hello: When I run version IEA-15-240-RWT-1.1.4 ([https://github.com/IEAWindTask37/IEA-15-240-RWT/releases/tag/v1.1.4] ) to calculate the aerodynamic response of the 15MW monopile wind turbine in steady wind Vhub=10.66m/s (Rated wind speed), the model runs fine, but the ServoDyn module seems doesn't work. The GenPwr and GenTq equal to 0 over time, and RtAreoCp and RtAreoCt drop to 0. It could be an oversight in my setup, but after trying, I still can't find the problematic slip-up. So, I'm uploading the model file now and look for help.

Steps

  1. Download IEA 15MW from the github repository (v.1.1.4)
  2. Download OpenFAST 3.4.1 (last compatible) executable from github repository
  3. Download libdiscon.dll from ROSCO controller (v2.7.0) library and compile successfully
  4. In "Inflowfile.dat", set the "WindType=1 (steady wind)", and set the horizontal windspeed to 10.66m/s
  5. In"IEA-15-240-RWT-Monopile.fst", turn on the function switch "CompElast", "CompInflow", "CompAero", "CompServo", and setting the input file location.

    Looking forward to replying!

gbarter commented 1 year ago

Is this still an issue? I think you might need to be using the latest OpenFast (v3.5.1). Your message suggets you are using 3.4.

DLUT-cabbage commented 1 year ago

Hi @gbarter: So grateful for your reply. As per your suggestion I updated the version of OpenFast (v3.5.1) and tried again but still not resolved. For testing, I did the following settings for _IEA-15-240-RWT-MonopileServoDyn.dat: PCMode=0 and VSContrl=1, and the results are as follows. It looks like the generator will start if pitch control mode is turned off. So is it possible to troubleshoot the problem? Fig 21-12D-1 I've uploaded the model for ease of communication. Anyway, thanks again for your reply and admiration for the work you and your team have done! https://github.com/DLUT-cabbage/Learning-Edition-Openfast-v3.5.1

Hi,

I'm not exactly sure what your target is or the issue. I recommend using the models provided in this repo on the develop branch and changing them incrementally until they reach your desired target. You'll also want to use ROSCO v2.8.0.

Best, Dan
